How to install a second Diablo 2 on my computer?

Hey folks, how do I install a second Diablo2 on my computer?
Seems the CDs install file locates the first copy and therefor I canT install a second one even thought I have 2 CD-keys.
Any help would be great, might be odd that and "old fox" like me donT know this but have never bothered before. Sadly its a bit harder nowadays to find ppl on when you need a mule, so a second CD-key would solve that.

I always use VMware to emulate another windows XP (each copy eats up ~3GB of disk space and 192MB RAM when activated). Works just great.
Of course, this would require another set of cd-keys (d2+d2:lod), and you will be tempbanned A LOT more often when using two accounts with the same IP-address, so be careful.

Will have the last part in mind, and will try this if the renaming donT work.

Just got my second copy running with the free version of sandboxie. Works like a charm

You just have to rename your diablo 2 folder and delete the desktop shortcut (might have to delete the start menu shortcut as well). You don't have to do anything fancy with sandboxie. You rightclick and and chose "run sandboxed" on your second installation to get them running at the same time.

You can run multiple accounts on a windows machine without sandboxie and not get the "only one copy of Diablo II may run at a time" error. You have to use fast user switching. Setting up fast user switching varies depending on what version of windows you use however, and you didn't give the specs of your system, so I cannot help you further. Make sure to give your system specs before asking questions!

I considered user switching, but having two games running at once and being able to move your mouse between them is amazing. I have my second copy running windowed on my second monitor, but having it windowed "behind" works fine as well.
